The annual Heritage Foundation retreat for conservative lawmakers this week has been moved from Philadelphia as the city expects millions of people to flood the streets Thursday for a parade to celebrate the Eagles’ 41-33 Super Bowl victory over the New England Patriots.

Heritage officials have relocated the retreat to Washington, D.C.

“We are no longer planning to go to Philly because of security and logistical concerns associated with the big event in downtown Philadelphia,” a spokesman for the foundation told Roll Call.

Police arrested only four people, far fewer than headlines in the media or photos of the chaos on Twitter would suggest.

“The knucklehead contingent was extremely small,” Philly Mayor Jim Kenney said Tuesday at a press conference about the victory parade, which is expected to draw millions to the city. “The media focuses obviously on the negative.”

Still, Heritage is taking no chances on an event that hosts roughly three or four dozen conservative lawmakers each year to refocus and explore conservative movement ideals.
